adapted to be inserted in the production line for projectiles to bearmed with nose fuses, for use in cutting a staking notch in the nose ofa projectile.

The speciiic nature of the invention as well as other objects andadvantages thereof will clearly appear from a description of a preferredembodimentas shown in the accompanying drawing in which:

Fig. 1 is a plan view of the support of this invention disposed inoperative relation to a staking notch cutter and showing a projectile onthe work table movable in the direction of the arrow' toward thesupport;

Fig. 2 is a view partially in elevation and par tially in section takenon the line 2-2 of Fig. 1 looking in the direction of the arrows.

Referring now to the drawing by characters oi' reference, there is shownin Fig. 1 a work table Ill arranged in the production line forprojectiles II and adapted to receive the projectiles II in anyconvenient manner after certain prior operations thereon in the courseof production.

The table I0 may be suitably inclined to provide for movement of theprojectiles from left to right, as viewed in Fig. 1, under the influenceof gravity or otherwise arranged to facilitate movement of theprojectiles as desired.

A plurality of rollers I2 are journaled in the table I0 adjacent itsrightmost end as viewed in Fig. 1, with their axes disposed inparallelism with the direction of normal travel of the projectiles uponthe table. Each of the rollers I2 is so journaled in the table IIJ thatits upper surface projects a sufficient distance above the surface ofthe table III as to support a projectile II resting on the rollers withits rotating band or bands I3 clear of the table in order to preventinjury thereto in movement transversely of the table. To further ensurepreventing injury to the rotating bands I3 of the projectiles therollers I2 are suitably covered with any desirable material softer thanthe material of the rotating bands.

In alignment with the rollers I2 and disposed on the same side of tableIll as the noses I4 of the projectiles I I is arranged a conveyor rollerframe comprising spaced parallel side plates I5 secured to the bed frameof the staking notch cutter I8 or to any other suitable support, andhaving a plurality of hardened rollers I6 journaled therebetween in suchmanner as to receive a projectile II from the rollers I2 and con- Vey itin line forwardly. Movement of a projectile I I forwardly on the rollersI6 is limited by an adjustable stop plunger I'I, suitably secured to thebed frame of the staking notch cutter or other support, which engagesthe nose bore of the projectile to limit the forward movement of theprojectile on the rollers I6. In the instance illustrated two hardenedrollers I6 are employed, which are so arranged as to engage thebourrelet and body of a projectile, respectively, in lsuch manner as tosupport the latter with its axis in a horizontal plane. Moreover, theadjustable stop Il is so positioned relative to the rollers IB as toprevent forward movement of a projectile II thereonto an extent thatwill permit engagement of the rotating bands I3 with the rearmost of thehardened rollers I6. The stop I'I also, in addition to limiting forwardmovement of a projectile on the rollers I6, serves to rigidly supportthe nose of the projectile during the staking notch cutting operation tonext be described.

The staking notch cutter I8 supported by its bed frame is arranged tocut a staking notch in the nose of the projectile in a plane of its axisas the projectile is urged forwardly on the rollers I6 against thecutter and adjustable stop Il.

After a staking notch is cut in the nose of the projectile it iswithdrawn from the hardened rollers I5 to a position upon the rollers I2With its rotating bands I3 clear of the rear end of the work table IIJand transferred by means of a table, which may be a continuation of worktable ID, to another work station.

Having now described a present preferred embodiment of the invention Iclaim:

l. In a support for projectiles in combination, a work table arrangedfor movement of a projectile thereon transversely of its axis, aplurality of rollers journaled in the table with their axes disposed inparallelism with the direction of said transverse movement adapted toreceive and convey a projectiie longitudinally of its axis, a pluralityof conveyor rollers disposed on one side of said work table in alignmentwith said work table rollers adapted to receive a projectile from thelatter for continued axial movement, a stop supporting member providedforwardly of said conveyor rollers in alignment therewith, and alongitudinally movable stop mounted on said stop supporting memberarranged to be engaged by and support the nose of said projectile forlimiting axial movement thereof on said conveyor rollers. y t

2. In a supportrfor projectiles in combination, a work table arrangedfor movement of a projectile thereon transversely of its axis with itsrotating bands unsupported by the table, a plurality of rollers coveredwith a material softer than said rotating bands journaled in the tablewith their axes disposed in parallelism with the direction of saidtransverse movement adapted to receive and convey a projectilelongitudinally of its axis, a pair of hardened rollers disposed on oneside of said work table in alignment with. said work table rollersadapted to receive a projectile from the latter for continued axialmovement, a stop supporting member provided forwardly of said conveyorrollers in alignment therewith, and a longitudinally movable stopmounted on said stop supporting member arranged to be engaged by andsupport the nose of said projectile to limit its axial movement upon thehardened rollers to a position where the rotating bands of theprojectile do not engage the rollers.

3. In a support for projectiles in combination,

a work table arranged for movement of a projectile thereon -transverselyof its axis with its rotating bands unsupported by the table, aplurality of rollers covered with a material softer than said rotatingbands journaled in the table with their axes disposed in parallelismwith the direction of said transverse Ymovement and their upper surfacesprojecting above the upper surface of the work table a distance greaterthan the depth of the exposed parts of said rotating bands adapted toreceive and convey a projectile longitudinally of its axis, a pair ofhardened rollers disposed on one side of said work table in alignmentwith said work table rollers adapted to receive a projectile from thelatter for continued axial movement, said hardened rollers be-V ingarranged to support the projectile with its axis in a horizontal plane,a stop supporting member provided forwardly of said conveyor rollers inalignment therewith, and a longitudinally adjustable stop mounted onsaid stop supporting member arranged to be engaged by and support thenose of said projectile to limit its axial movement upon the hardenedrollers to a position where the latter only engage the bourrelet andbody of the projectile forwardly of the rotating bands, respectively.
